Elliot and Harriet “Hunny” Reinken (pic tured) have been married longer than many adults have been alive, and they’re sticking with it.

“My husband turned 87,” said Hunny, 81. “And he’s still good-looking and still a good kisser.”

“They all tell me that,” Elliot chimed in.

“Watch it, Elliot.”

From Kelsey Grammer to Tiger Woods, from Jesse James to Al Gore, men are discarding perfectly good mates at a furious rate, but divorce itself may be going the way of the polar bear. A recent Pew survey determined that Americans are getting hitched at the lowest rate in history. Folks can’t be bothered to give it a try.

Headline-grabbing bust-ups don’t help. Al Gore and Tipper threw in the towel after 40 years of marital pretense. And though they’ve been photographed together this week, newlyweds Chelsea Clinton and Marc Mezvinsky are living apart, on opposite sides of the country.

There is good news in Gotham. A Post survey found that a whopping 80 percent of married people, given the chance to redo their lives, would chose to love the one they’re with.

Today is Valentine’s Day. The day devoted to love, flowers and mushy greeting cards seems a fine time to check in on duos so crazy in love — or just so crazy — they can’t imagine life apart after more than half a century.

“My life would not be too easy or complete without her in my life,” said Louis, a retired fire lieutenant. “It’s one of the best things that ever happened to me, meeting her.”

Awww!

A few common themes emerged in the hunt for the secret to lifelong bliss.

These couples married young, most during and just after World War II, a time when psychobabble like “getting in touch with one’s feelings” had yet to be invented and Dr. Phil and Oprah had yet to be born. A shared sense of humor is critical to marital longevity. Children, grandchildren and great-grandchildren — who go home at night — don’t hurt.

“We have no choice but to love each other!” laughed Fortunato Corso of Bensonhurst, who’s been wed to Maddalena — are you sitting down? — 70 years.

Each was 17 when the couple wed in Italy. Daughter Madeline suspects her parents’ passions still run warm.

“You sleep with your door closed. Do you still fool around in bed?” she asked her mom and pop. “They never answered.”

“We stuck together. It’s not like we planned it. We didn’t read any books,” said Joe Mark of Midwood, married 66 years to Georgia. They met on a blind date — with other people — and quickly decided they had to be together.

At 88, said Joe, sex “is in the mind now. In the morning, I get up and ask, ‘How was it?’ She says, ‘Great!’ We’re friends, and we laugh. I still make her laugh. And if we have to dance, we dance.”

Today, Brooklyn Borough President Marty Markowitz is renewing the marriage vows of couples who’ve been wed 50-plus years, an event that attracts hundreds of pairs (and a few youngsters looking to score free champagne).

Hunny and Elliot will think of their double wedding — Hunny’s twin sister, Bunny, married Elliot’s twin brother, who has since died. For years, they sang as a quartet.

Love, romance and good sex is not the sole property of the Victoria’s Secret crowd. It actually improves when one is not looking in the mirror.

“I look around and I really see the value of Elliot,” Hunny said. “The pluses outweigh the minuses, which makes me believe I was right all along.”

On Valentine’s Day, be nice to the person you’re with. You might be stuck together a long time.

Call penalty on the adults

Turns out it does take three to tango. Eliza Kruger, the 17-year-old high-school kid who boasted that she “hooked up” with Jets quarterback “MARK F – – KING SANCHEZ” in his Jersey abode, was a regular on the Manhattan club scene, along with someone who should know better: her mom Marie, The Post reported.

I have little regard for a full-grown athlete who takes home a girl who hasn’t yet made it to her prom. A child too young to drink or vote. But a reader pointed out that the questionably chaperoned young lady frequented clubs intended for adults over 21. “I think her mother and that establishment should take some responsibility,” he wrote.

With an alley cat for a mom and no adult present (that means you, Sanchez), a child’s deviant behavior looks ordinary.

You’re still paying for this former prostitute

Hooker-turned-teacher Melissa Petro, who left her job at The Bronx’s PS 70 in disgrace, wants to work for “social justice” — by getting her paws on teenagers (!) at risk for sexual exploitation. Here are some gems that have sprung from Petro’s well-worn lips:

“I wouldn’t want my daughter to be a sex worker. I wouldn’t discourage her, either,” Petro told a dumbfounded Department of Education investigator. She also blurted that the “stigmatization and criminalization of sex work is the greatest factor in making the sex industry dangerous.” I guess pimps don’t exist on Planet Petro. Also traffickers, drugs and sexually transmitted disease.

Now you, the taxpayer, get screwed without a kiss. With teacher layoffs on the horizon, Petro, who’s been paid her $61,000-a-year salary ever since she was thrown out of the classroom last fall, will continue to draw her pay through April. Nice work.

The louse of representatives

Married upstate Rep. Christopher Lee, who resigned from office last week, may be the stupidest man ever to serve in Congress. He sent a cheesy, shirtless photo to a lady he met on Craigslist, and tried to pick her up by saying, “I’m a very fit fun classy guy.” I wish I could un-see that.

Then again, it appears that the randy Mr. Lee, at 46, has spent as much time in the Capitol gym as on the House floor, maintaining good muscle mass and well-defined abs. There is a future for a middle-aged hottie. Cialis could use a new pitch man.

Mike’s two ethnic slaps

Mayor Bloomberg took a humorless shot at all people of Irish descent, cracking last week that his neighbors at the Irish Historical Society on the East Side are “totally inebriated, hanging out the window.” That humdinger wasn’t even the most offensive part of the gag.

He also said, “I know that’s a stereotype about the Irish, but nevertheless, we Jews around the corner think this.” Speak for yourself, joker.
